Agressive and independent, agent Rachel Porter has long been a thorn in the side of the U.S. Fish and Wildlife Service -- and for her sins, she's been assigned to remote Montana. In this cold, windswept country of private militias and survivalists, grizzlies are being killed at an alarming rate. And while following up on a rumor that someone from the local Blackfeet tribe is responsible, Rachel uncovers an even more terrible truth: Native Americans are mysteriously disappearing as well. In this land that the Unabomber called home, it appears that endangered animals and humans are equally fair game. And the next casualty may well be one gutsy wildlife agent who refuses to let sleeping bears lie.
